. SAMUEL W. WEISS, o NEWARK, NEW E EY. ASSIGNOB GLO ART EG- EANY, 0F NEWARK, N JER$EY, acolm nerl u NEW YORK- LOCK;

To all whom it may concern:

Be it known that I, SAMUEL W. lVEIss, a citizen of theUnited States, residing in the city of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Locks, of which the following is a. full, clear, and exact description,such as will enable others skilled in the art to which it pertainsIto make, construct, and use the same, reference being had to the accompanying drawings,

shall be extremely inexpensive of construce tion and durable as to its wearing qualities.

With these ends in view, my invention consists in a push button or ring for releasing the bolt of suit case locks and in certain details of construction and combination of parts, as will be hereinafter described and particularly recited in the claims.

These objects I perform in the preferred embodiment of my invention, which I have illustrated in the accompanying drawings, to which reference is had, andv in which sim. ilar reference characters indicate corresponding parts in the several views.

In the drawings, I

plan views of the locking plate, the tumbler,

and the latch plate, arranged in the order in which they are assembled in the case.

Plate of my improved lock, to the rear of which a box-like, sheet-metal lock. case 2 is secured by means of rivets 3, whic h. pass throughears or lugs 4formed' integral with the lock case.2. The. faceplate. 1 isprovided with an opening 5, intended for the reception of a slotted hasp stud 6, carried by a. spring-actuated hasp/Z, which is. pivotally mounted'in a haspplate 8 and fastened the box-like lock case 2, so that the guidestuds,1010 pass through the slots 12, by means of which. thelock plate is held in position in the'lock case and is permitted to move back and forth. The lock plate 11 is provided, with a centrally-arranged apercure 13, for the reception of a key, which is designed to be applied to the key post 9. The lock plate. 11 is further provided with a stud 14, projecting upwardly from the lock plate, to, be engaged: by either one? of the notches or recesses 15 and 15 formed onthe lower edge of the spring-actuated, pivoted tumbler 16, which in assembling the device, is placed on top of the lock plate 11, and pivotallyearranged upon one of the guide studs 10, as clearly indicatedby the arrow, said. guide stud v10 passing through an, aperture formed in an. I ear, 17 of the, tumbler;

One endlof the tumbler 16 isfurther pro: vided with an integral extension 18, designed. to receive a helical spring 19, one end of said spring 19 engaging with the inside of the lock case 2, exerting a constant effort to press; one of the notched or recessed portions of the tumbler 16 against the stud 14 of the lock plate 11. a

The sheet-metal latch plate 20 is provided with a slot 21, which slot is intended to re- The face plate 1 is ceive the stud 14 of the sheet-metal lock P t 141, an y means Qf w ichi is Desitioned in the lock case 2 and permitted to move back and forth. The latch plate 20, at its front end, is reduced so as to provide a beveled latch 22, which is guided by and reciprocates in an opening 23 formed in one edge of the lock case 2. Movement of the latch plate in either direction is limited by the slot 21 and the shoulders 24 formed on the latch plate 20 adjacent to the beveled latch 22.

The lower end of the latch plate 20 is also provided with an integral extension 25, designed to receive a helical spring 26, said spring exerting a constant effort to keep the shoulders 24 of the latch plate 20 in engagement with the inside wall of the lock case 2 near the opening 23. The key button 27 is in the nature of an embossed ring, the rear of which is provided with integral tongues 28, designed to pas through suitable slots formed in the face plate 1 and to engage with apertures 29 located in the latch plate 20, to which it is secured by clenching the ends of the tongues 28 over on the under side of the latch plate 20. The button 27 beingthus secured to the latch plate 20, serves as a means for moving the latch plate to disengage the beveled latch 22 from the hasp 7, and the opening in the button 27 permits of the insertion of the key.

The moving parts, namely, the lock plate, tumbler and latch plate are of such shape as to lend themselves readily to manufacture by the use of suitable punches and dies from ordinary sheet metal.

V'Vhen the parts. are in the position shown in Fig. 2 of the drawings, they are unlocked. When it is desired to lock the latch plate, the key is inserted and turned, thereby raising the tumbler and causing to disengage the recess 15 thereof from the stud 1% of the lock plate 11, and throwing the lock plate 11 into the position shown in Fig. 3, simultaneously causing the stud 14 to be engaged by the recess 15 of the tumbler. The parts now occupy the position shown in Fig. 3, and it will be seen that the latch plate cannot be moved. Owing to the construction of the latch plate, which is provided with the large central aperture 80, and also to the fact that the push button or ring is secured thereto, the latch plate, by means of said push button or ring, can be moved back and forth, without removing the key, namely, while the'key is in the lock. y

Experience has demonstrated that the organization above described is a highly efficient one, and while I have shown the preferred embodiment of my present invention, I do not wish to be limited to the exact details of construction, combination and arrangement herein set forth, it being obvious that minor variations thereof, not involving the exercise of invention, may be made by any skilled mechanic, and such departures, not involving the exercise of invention, I consider within the scope and terms of my claims.

I claim:

1. In a hasp-lock, the combination with a face plate and a hasp, of a lock-case fastened to the back of the said plate, a spring-actuated latch plate located in top of said case and engaging with the hasp, a push ring slidably mounted upon the face plate and secured to the latch plate and co-acting therewith for disengaging the same from the hasp, a lock plate slidably located in the bottom of said lock case and slidably connected with said latch plate, and a spring-actuated tumbler interposed between said latch plate and said locking plate, pivotally connected to the lock case, and engaging with the lock plate for holding the parts in operative position.

2. In a hasp-loek, the combination with a face plate and a hasp, of a lockease fastened to the back of the said plate, a spring-actuated latch plate located in the top of said case and engaging with the hasp, a push ring slidably mounted upon the face plate and secured to the latch plate and co-acting therewith for disengaging the same from the hasp, a lock plate provided with holding means slidably located in the bottom of said lock case and slidably connected with said latch plate, and a tumbler provided with engaging means pivotally connected to the lock case, said tumbler interposed between said latch plate and said locking plate, the said engaging means of the tumbler co-acting with the holding means on the lock plate for holding the parts in operative position.

3. In a hasp-lock, the combination with a face plate and a hasp, of a lock case provided with two alined studs, fastened to the back of said plate, a spring-actuated latch plate located in the said case and engaging with the hasp, a push button slidably mounted upon the face plate and secured to the said latch plate and co-acting therewith for disengaging the same from the hasp, a lock plate provided with alined slots, said slots designed to receive the said studs, slidably located within said lock case and slidably connected with said latch plate, and a spring-actuated tumbler pivoted to one of said studs and engaging with the lock plate for holding the parts in operative position.

This specification signed and witnessed this 19th day of October, 1917.
